I have worked my way through all of the challenge games at expert level. I still have a handful in each island group that I can't beat, and I am working on patience and due diligence. I was thinking that it would be useful to have a good terminology base to work from to describe how to beat an island. Does anyone know of a good system for hex mapped games? Here is what I thought of:
1) Imagine a rectangle that would enclose the entire island and extend the hexes to fill the rectangle.
2) Count across the top of the map with alphabetical labels and down the left side with numerical labels. Keep the labels lined up following the stagger of the hexes. The top left corner is A1. The hex below it would be A3. The top hex in the next column would be B2 and the hex below it would be B4.
3) Each move would be described by first giving the hex address of the Home for the area to be selected, then either M for move, C for create, or P for promote, then the hex where the action happens.

As I describe this, it all sounds hopelessly tedious, and it might just be more fun to let Dark Green win a few more times until I figure out the way to beat him.
